Abstract
An exhaust system includes an exhaust duct having an internal surface defining an exhaust gas passage extending along an axis, at least one sensor opening in the exhaust duct that is configured to receive an exhaust gas sensor, and a sensor housing positioned within the exhaust gas passage. The sensor housing has a wall that extends at least partially around the at least one sensor opening. The wall has an inner wall surface defining an internal volume and includes at least one outlet opening. At least one tube is in fluid communication with the internal volume and extends from a first end, which is open to an inlet of the internal volume, to a second end that is distal from the first end. The at least one tube includes a plurality of inlet apertures.
